Decircular NPM

decircular

Remove circular references from objects

Circular references occur in JavaScript when an object references itself or creates a loop of references involving other objects. This can lead to issues like infinite loops and errors during serialization (e.g., with JSON.stringify). This package replaces circular references in objects or arrays with clear path notations (e.g., [Circular *a.1.b]). Ideal for data serialization, debugging, and logging.

Install

npm install decircular

Usage

import decircular from 'decircular';

const object = {
	a: 1,
	b: {
		c: 2
	}
};

object.b.d = object.b; // Creates a circular reference

console.log(decircular(object));
/*
{
	a: 1,
	b: {
		c: 2,
		d: '[Circular *b]'
	}
}
*/
